In some carpools, each carpool member takes turns driving their own vehicle, while in others there is only one driver. There is no hard and fast rule - it is totally dependent upon the individual circumstances of those in your carpool.

This is perhaps one of the key questions asked by potential carpoolers and, unfortunately, there is no simple answer. In carpools where driving is equally shared, no money usually changes hands as each member is using their personal vehicle an equal amount of time. When only one person does the driving, or when there is an unequal split of driving responsibilities, the cost-sharing arrangement must be discussed by those in the carpool. The carpool members are free to base the costs on whatever they may choose. For comparison, check out current transit fares at www.halifax.ca/metrotransit/tickets.html

Depending on your vehicle and driving patterns, the cost per km of driving a vehicle can range from approximately $0.40 to over $0.80 per kilometre. (see the Canadian Automobile Association (CAA) at www.caa.ca If you can share in the cost of commuting to and from work by carpooling with others, your potential savings are significant.

No! You can carpool every day or only a few days a week. You and your carpool members decide upon the schedule. Some people even belong to two carpools - you may carpool with one carpool on Mondays and Wednesdays and then join a second carpool for the remainder of the week.

Being late, or having to wait longer than anticipated, is one of the most common reasons why carpools fail. Just like a bus, carpools work best when they are on a defined schedule. Being on-time is just as important in a carpool as it is with transit. Each carpool should have clearly defined guidelines for how long they will wait.

If the other members of your carpool don't have similar arrangements, make the day-care centre or the school your pick-up and drop-off point. That way you can schedule your pick-up time to correspond to the time when you know your child is happily settled in for the day.

Note: If you are going to have a pick-up/drop-off point different than your home postal code, just make sure you enter the origin and destination address of the location where you would like to be picked up and dropped off.

If you know you have to work late on a particular day then don't carpool. Carpooling is meant to be a flexible and convenient arrangement. On those days when it is not convenient, commute to work in another manner. Take the bus, your bike, walk, telework or bring your own car.
